Be it knownthat LJACOB BECK, a citizen of the United-States, residing at Schenectady,"county"of Schenectady, State of New York,' have invented certain new and useful This inv ntion relates to sheet-metal-working-machines, and its object is primarily to,

providean automatic machine for making the sheet-metal shells for the sockets of in- 'candescenbelectric lamps, though it is oapa' bl qf operating on cup shaped blanks of r sheet-:rnetal for any purpose.

Fig. 18 is aperspective view ofthe part side elevation of the malefaiid fe male diesv for punching the side holes. 20 and 21 arethe male dies for punchin'gland countersinking the holes "in the" offthe shells. a The frame 1 of the machine is a 'jstoutftable-like; structure, near each end of which and 5, which engages at'regularintervals witha spur-gear 6, sec'ured to the face of one cf the" on its front side is located'a large 'sprocketprocket wheels. The "mutilated gear is keyed ona shaft 7, running across thefra'rne 1 and'gear'ed to the main shaft 8, which1'is 'located lengthwise of the'machineat itsre'ar and. is journale'd in"bearings,preferablydn" brackets 9, rising from the 'rearofthe frame 1'. The main shaft is driveniby -a belt fpiilley l0, and its connection.with thatransveijse shaft 7 is preferably by means offspurfgears 11, a counter-shaft 12,-and be el-genera.

The carrier-chain is locked aftenachrhdvement by a spring-pressed bolt 14, lbngitudinally movable in a'brackct 14 toward-the face of the gear 6 and'engaging with'so'ckets 15 in the spu'r gear 6. I 4 tilate'd gear 5 engages a collar 16, the bolt .14 near its operativefend at draws the bolt justbefore'theftoothe ment of the gear 5 engages the 'gearb.

The anvil 98, which holds the stationary die of the punch, lies close in front of the-chain} so that the blank is held in itshole in the (position tobeoperated on by the punch an die which cut out the middle portion of the end of the cup-- shaped blank and also form two small holes in the flange that remains, as clearly shownm Fig. 15. The chain en feeds the blank along to a position in li e with the punch 99,

as shown in Fig. 21, which is similar in construction and operation to the other. This punch countersinks the two screw-holes in the flange of the blank, as shown in Fig. 16, the blank still remaining in the hole in the carrier-chain. The next movement of the chain brings the blank; to the upright unch 100, actuated by acra'nk-s'haft 101, w ich is driven from the main shaft 8,preferably by an endless-chain belt 102 and sprocket wheels 103. The blank is moved out from 1 he carrier-chain and under the punch by a short suitable arm on a reciprocating bar 104, which slides in a bearing 105 and is pivotally connected with a slot in a rock-arm 106 on a.

short rock-shaft 107, actuated by=the main shaft 8, preferably by an eccentric 108 on said .main shaft, provided with a strap 109 and rod 1 10, the latter being, pivoted to the rock-arm106. p The reciprocating bar 104 extends out over the chain 3 and has secured-near its end a cross-bar 115, provided withejectorfingers The finger 116 is rigidly connected thereto and serves to eject the comleted shell from the. chain, and finger 117 is ongitudinally. movable in the bar 115 fora purpose to be presently described. The 'outer'end of finger 117 is bored out for the reception of a spring 118, and the endof a resser-rod 119, carried by an arm' 120,'fixed to the outer end of bar 104;; A crank-arm 121 is secured to the middle of the fingera nd.

When a shell' is presented .to the female die 1 24 by, the finger11 7,the'sleevel28=engages theu'pper edge of theshell and travelsback finger 11.7 prevents the shell from tilting,

as it is liable todowhen not held at both ends; I

The" punch 100 carries a toe apiece 136,

which'extendsbelow the end of the punch and between the endofthel die 124 and the I end of the finger 117 the latter yieldingun der the action'of its spring 118, and-operates to bend in the bottom edge of the portion to be removed from'the'shell by the punch 100. The shell isstripped fromthe die 124 by a rock-arm 113 n the rockshaft 107 and en- 'st-ripping rodigl 1, actual ed by a dog 1.12.on a

gaging at its orward end with a head 132, in

which are set two small rods 1 33 which extend longitudinally through the female die 124 so as to engage the inner ends of the shells upon the comple-Qio'nof'thepunching operation.

The head 132 is normally pressed rearwardly by a spring 134 engaging therewith and with a socket 135'in the rear end of the die 124.. the'shell is finally forced from' the chain by finger 116 it'falls into a. trough 114, by"

which i tfisdefleci'ed-to suitable receptacles.

The opera; ion of the machine may be briefly Y recapiiulated as. follows: The cup-shaped blanks OfsheetmeLal are fedby the plunger 1 117-into the/holesfin the carrier chain 3, by 'whibh trey are Inovedf inierni-ittingly fron one'to norher of the operai'ingmechanisms.

.withit under the pressure e erted'jby-the chain. A further movement brings'itin line Y with the punch '99, which countersinks the two screw-holes. The final operat1on- 1s performed-b the unch'100 which cuts out a Y P. 7

port ion of the side .of the blank afterit has been pushed out of the carrier-chain by the bar 104. The finished product is stripped from the punch by the stripping-rod 1 11 and reiurned to the chain and carried opposite ejector-finger116,.vhere it IS forced out and falls down the spout 114 to a sun able receptacle- &
